Google TV is the easiest to get rid of ads on. I have a Sony and a Hisense both no ads.
Look up and use the Projectivy Launcher.
You'll also want to sideload an app that forces the default launcher to Projectivy (can't recall the name) because they don't allow changing it through the stock OS. Projectivy tries to use accessibility settings to take over on its own, but it breaks some other features so I don't use them.
The protests didn't make nearly any national news. Hope the next ones go better.
